There are better palettes for viz work, the most common being viridis. Read more here:

@osma @kate @simon the point of the colours on the National Grid site is not to show a continuous range in any way. It's the opposite - the aim to show discrete things. The blue thing and the cyan thing are just as distinct as the red thing.

Right. When that's the objective, the palette would ideally be one which is distinct even with color sight issues, which rainbow is not. That's not an easy target though! Combining colors with symbols, patterns, border widths etc are things that could help. When I was studying the topic, this was a helpful post:
